SWANSEA swimmer Jazz Carlin has spoken about her Olympic Trials nightmare but revealed her London 2012 dream is still alive.

Carlin suffered glandular fever last year and has not returned to the form which saw her claim two medals at the Commonwealth Games in Delhi in 2010.

The 21-year-old failed to qualify for a place in the 400m and 800m freestyle events and her final chance now rests at the second Trials in Sheffield in June, with one 200m individual and two relay spots up for grabs.

“It has been a tough year and my worst nightmare,” said Carlin.

“The last thing you want is to be injured or ill because things are out of your hands and you can’t control things.

“When you have put in so many years of getting up at 5am in the morning and doing all the hours of training, to get ill is such a huge disappointment.

“I was hoping I would qualify in March and training had been going really well but it did not happen in that week.

“But I have to focus all my attention onto June.

“There is still a space in the 200m individual event and the relay.

“I have taken a knock but I have to get back on track.

“It would be such a big thing to be involved in a home Olympics and hopefully I can qualify.”
